Research on the Technical Condition Evaluation and Disease Treatment Scheme of the Existing Highway
In order to ensure the driving safety of existing highways,this paper takes an expressway as the research object,and uses the automatic+manual detection method to evaluate the technical condition of asphalt pavement from the aspects of pavement damage,flatness,rutting and deflection.At the same time,the application of direct grouting,slotting grouting,milling and paving schemes in the treatment of asphalt pavement crack disease and rutting disease is expounded.The research results can provide reference for similar projects.
